LCFPD Environmental Educator Jennifer Berlinghof has been out at Ryerson with her drill, hammer, spigot and pail to tap a few mature, sugar maples. She said the sap which is very watery has to be processed.

“It takes about 40 gallons of sap to produce one gallon of syrup. It takes a lot of boiling,” Berlinghof said.

She pointed out that the resulting maple syrup becomes a tiny taste treat given to people on the March hikes.

Hikes are every half hour from noon to 2 p.m. starting at the Ryerson Woods Welcome Center, 21950 N. Riverwoods Rd., Deerfield, but preregistration is necessary.

Cost is $6. Children age 3 and under, free. To register and get more details call (847) 968-3113 or visit LCFPD.
